Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. Statement 39
Warning Incorrect connection of this or connected equipment to a general purpose outlet could result in a hazardous situation. Statement 87
Setting Up the Chassis
You can set the chassis on a desktop or install it in a rack. Use the procedure in this section that best meets the needs of your network:
•Setting the Chassis on a Desktop
•Rack-Mounting the Chassis
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017
Setting the Chassis on a Desktop
The location of the chassis is extremely important for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. The following information will help you to plan the location of the chassis:
•Plan for access to both front and rear panels of the chassis.
•Ensure that the room where the chassis operates has adequate ventilation. Remember that electrical equipment generates heat. Ambient air temperature may not cool equipment to acceptable operating temperatures without adequate ventilation.
Attach the rubber feet as shown in Figure 3-1. Rubber feet are included in the accessory kit that shipped with your Cisco AS5400XM universal gateway.
Figure 3-1 Attaching the Rubber Feet
Rack-Mounting the Chassis
This section describes how to rack-mount the chassis. The Cisco AS5400XM universal gateway arrives with 19-inch (48.26-cm) rack-mount brackets and larger brackets for use with a 23- (58.42-cm) or 24-inch (60.96-cm) rack. (See Figure 3-2.)
The following information will help you plan your equipment rack configuration:
•Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.
•When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated in the rack.
•Baffles can isolate exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can be found by experimenting with different configurations.
•When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the equipment by itself, if possible. Power down other equipment in the rack (and in adjacent racks) to allow the unit under test a maximum of cooling air and clean power.
•Install the chassis and external devices to which it will connect in a contiguous stack.
Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. Statement 12
Required Tools and Equipment
You need the following tools and equipment to rack-mount the chassis:
•Number 2 Phillips screwdriver (not included)
